다국어 초록 (Multilingual Abstract)

An experimental study is presented for the contact property of the interactions between road wheel and track link in order to identify the dynamic characteristics of the high mobility tracked vehicle along the verical direction with loading conditions. The revolving rubber molded track link and road wheels are subjected to the high impulsive contact forces from the ground, and the traction forces from the engine which lead to the tension, compression, and torsional load as the operational conditions and environments. The mechanical characteristics of the track links interconnected by rubber bushings and pins so as to simulate the dynamic analysis of a high mobility multibody tracked vehicle by using empirical methods are also presented. In this investigation, the dynamic and static effects of stiffness and damping coefficients are taken into consideration of the vertical, radial and torsional interations between double pin track links and road wheels. The static and dynamic loadings, and frequency response of these coefficients of track links of high mobility tracked vehicle are represented, respectively.<br/>
